need some sweetness

I've been brewing a pale ale for a bit now. It tastes fine but I would like to add sweetness. In a 10 gallon batch, I use american 2-row, 3lbs vienna 1 lb cara pils and some C-40. I have been using nottingham yeast and fermenting in my 58 degree basement.

I am looking for a clean but sweet finish like on a Sierra Nevada or a longhammer IPA.

The yeast ferments out to 1.006 or so. I was thinking that maybe I should use a different yeast.

Go Sox,

Maybe a little bit of honey malt, even .5 lb will go a long way in a 5g batch. I hope that helps!!!
